National Weather Service extends tornado watch in area parishes to 5 a.m.

A tornado watch advisory remains in effect for Ascension, Jefferson, Livingston and Orleans parishes, and has been extended until 5 a.m., according to the National Weather Service.

The watch also includes Assumption, Jefferson Lafourche, Plaquemines, St.Bernard, St. Charles, St. James, St. John The Baptist, St. Tammany, Tangipahoa, Terrebonne and Washington parishes, a weather advisory reported.

A tornado watch designates that conditions are favorable for a tornado to form, weather authorities said.

In Livingston Parish, the National Weather Service’s website shows that the sheriff’s office reported to them a tornado touchdown at around 8:20 p.m. near La. 63 and La. 442. There were trees down, according to the report.

Another report from the sheriff’s office to NWS described a brief touchdown around 7:50 p.m. and damage to fences near Denham Springs.

In a phone interview, Denham Springs-resident Ryan Moran said he pulling into his driveway with his family just after 8 p.m., when he saw a tornado approaching their subdivision.

“We ran in the house,” he said. “It lasted about 20 seconds and when we came outside, there was damage everywhere -- garage doors, fences, flipped-over trampolines.”
